Well, better ask directly the manufacturer or the seller (who should ask the manufacturer) or ask directly at some offical asus reseller's contact page. BTW for me the 750G is too big, I'd prefer a 15" version (it was available 2 year ago I think, now nothing).
The ASUS ROG G750JM-DS71 available on Amazon appears to be the Maxwell chip as it has 2GB vs the Kepler's 4GB of DDR5? I think this is the only way to know what chip is in there, the "details" are not that detailed when it comes to specifying Kepler or Maxwell. Perhaps the manufacturer's box will specify?
Thanks a lot for this article. I was seriously thinking about that Clevo P150SM-A. I've thought the 860M MXM was already a keppler card (I know 870M+ are the old ones). Looks like I still will have to wait a bit :D
The unequal duel. Nvidia offers two different versions of it latest high-end GPU GeForce GTX 860M. Besides a version based on the Maxwell architecture, there is also a GPU from the old Kepler generation. We compared the performance of the two DirectX 11 chips and found a winner.
